.curl: (35) error:1408F10B:SSL routines:ssl3_get_record:wrong version number

[solutionall]

After I installed BigBlueButton using install.sh I got this error:
curl: (35) error:1408F10B:SSL routines:ssl3_get_record:wrong version number

And I can't connect https://bbb.MYDOMAIN.com - it gives me: This site can’t provide a secure connection
I tried to connect with external ip, local server ip then it gives me: Welcome to nginx!

What configuration I missed? Please help me guys..

I tried many many times.

Here is /etc/hosts file:

127.0.0.1 localhost
127.0.1.1 bbb
66.66.88.88 bbb.mydomain.com

This is result from bbb-conf --check

curl is trying to do a local connection to your server and check that the BigBlueButton API is available at.

curl -sS https://bbb.mydomain.com/bigbluebutton/api

Try adding --verbose

curl -sS https://bbb.mydomain.com/bigbluebutton/api --verbose

to get more information on why its failing.
